人们对激射波长在０．９＜λ＜１．１μｍ的应变ＩｎＧａＡｓ／ＡｌＧａＡｓ量子阱（ＱＷ）激光器很感兴趣。主要应用有泵浦晶体或玻璃主体中的稀土离子（特别是掺Ｅｒ３＋光纤放大器的９８０ｎｍ泵浦），研制透明衬底的面发射激光器和增加倍频二极管激光器的可用波长范围。本文叙述了多种结构应变ＩｎＧａＡｓ／ＡｌＧａＡｓ单量于阱激光器的工作特性。
There is great interest in strained InGaAs / AlGaAs quantum well (QW) lasers with lasing wavelengths of 0.9 <λ <1.1 μm. The main applications are rare earth ions in pumping crystals or glass hosts, especially 980 nm pumps doped with Er3 + fiber amplifiers, to develop surface-emitting lasers for transparent substrates and to increase the usable wavelength range for frequency doubling diode lasers. This article describes the operating characteristics of a variety of single-quantum well InGaAs / AlGaAs traps with structural strain.
